Explanation:
the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117/450, or 26 percent.
Consequently, plants can at best absorb only about 34 percent of the incident sunlight. The actual percentage of solar energy stored by plants is much less than the maximum energy efficiency of photosynthesis. An agricultural crop in which the biomass (total dry weight) stores as much as 1 percent of total solar energy received on an annual areawide basis is exceptional, although a few cases of higher yields (perhaps as much as 3.5 percent in sugarcane) have been reported. There are several reasons for this difference between the predicted maximum efficiency of photosynthesis and the actual energy stored in biomass. First, more than half of the incident sunlight is composed of wavelengths too long to be absorbed, and some of the remainder is reflected or lost to the leaves
A group of Chinese women with PCOS who were receiving treatment saw several metabolic and hormonal imbalances improve after taking BBR. The primary consequences may be connected to the modifications in body composition in obesity and dyslipidemia. For the evaluation of the possible beneficial metabolic effects of BBR in women with PCOS, additional controlled trials are required.
PCOS:
- Objective: Insulin resistance is a common metabolic and reproductive condition called polycystic ovarian syndrome (PCOS) (IR). A quinoline derivative alkaloid known as berberine (BBR) has been utilized as an insulin sensitizer and is isolated from Chinese medicinal herbs. There may be a therapeutic benefit for PCOS from BBR. The purpose of this study was to compare the effects of BBR and metformin (MET) on the metabolic characteristics of PCOS-affected women.
- Design and methods: Ninety nine PCOS and IR patients were randomly assigned to one of three therapy groups: BBR+ compound cyproterone acetate (CPA;
), MET
CPA
, and placebo
CPA
for
months. Before and after the treatment period, metabolic and hormonal measures as well as the clinical characteristics of the women were evaluated. - Results: Reduced waist circumference, waist-to-hip ratio (WHR;P<
), total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDLC; P<
), as well as increased levels of high-density lipoprotein cholesterol (HDLC) and sex hormone-binding globulin (SHBG; P<
) were all observed following treatment with BBR as compared to MET. Similarly, BBR treatment decreased WHR, fasting plasma glucose, fasting insulin, homeostasis model evaluation for IR, area under the insulin curve, TC, LDLC, and TG (P<
), while increasing HDLC and SHBG (P<
) as compared to placebo.
